Lesson52 Hot snake触电的蛇
What caused the fire
At last firemen have put out (熄灭) a big forest fire in California. Since then, they have been (be) trying to find out how the fire began. Forest fires are often caused by broken glass or by cigarette ends which people carelessly throw away. Yesterday the firemen examined the ground carefully (care), but were not able to find any (一些) broken glass. They were also quite sure that a cigarette end did not start the fire. This morning, however , a fireman accidentally discovered the cause. He noticed the remains of a snake which was wound round the electric wires of a 16,000-volt power line. In this way, he was able to solve the mystery. The explanation was simple but very unusual. A bird has snatched up the snake from the ground and then dropped it on to the wires. The snake then wound itself (它) round the wires. When it did so, it send sparks down to the ground and these immediately started a fire.

fire的可数性（可数还是不可数）
① 泛指一般意义的“火”，是不可数名词。如：
Paper catches fire easily. 纸很容易着火。
Playing with fire is dangerous. 玩火危险。
比较以下各句（注意动词与介词的不同搭配）：
The house was on fire. 房子着火了（着重状态）。
The house took [caught] fire. 房子着火了（着重动作）。
He set fire to the house. =He set the house on fire. 他放火烧了房子（着重动作，且强调有意放火）。
② 表示具体意义的“火灾”或“炉火”等，是可数名词。如：
A fire took place in that street. 那条街发生了火灾。
There were several fires in this city last month. 上个月这个城市发生了好几起火灾。
It’s too cold, and I’ll make [build, light] a fire in the room. 我要屋里生个火。
但是，即使表示“火灾”，若不是指具体的一起的“火灾”，而是指意义较为抽象的“火灾”，它也通常是不可数名词。如：
Look out for fire. 小心火灾。
In case of fire ring the bell. 万一发生火灾，请按铃。
③ 香烟、火柴、打火机等的“火”，在英语中不能用 fire 来表示，而用 light。如：
Can you give me a light, please 劳驾，能借个火吗
④ 此外fire还有很多合成词，且它们就是在fire 和另一个词的意思组合上直译，如：
fireman / firefighter 消防员 firework 烟花 firecracker 鞭炮
firefly 萤火虫 fireplace 壁炉 firewood 柴火
想一想，类似fire用法的词还有哪些呢？
宾语从句用法复习：
Q1：什么是宾语从句？
首先，它是一种名词性（名词性/动词性/形容词性）从句，即这句话起到的是代指人、事、物的句子。
其次，它在主从复合句中充当宾语（主语/谓语/表语/宾语/定语/状语）的成分，位于及物动词、介词或复合谓语之后的从句，被称为宾语从句。
最后，宾语从句有三类：动词的宾语从句、介词的宾语从句、形容词的宾语从句。
Q2：宾语从句要遵守的三件事！
关于语序：宾语从句的语序一律用陈述句语序。
判断：Do you know who has won this game 你知道谁赢了这一局游戏吗
关于时态：记住以下口诀——主现从不现，主过从必过，从真永一现。
关于连接词：
① 宾语从句的从属连词主要有that , if , whether。
that引导表示陈述句的宾语从句，而if和whether引导表示“是否”的宾语从句。
e.g. :
He told me that he would go to the college the next year.
他告诉我他将在下一年上大学。
I don’t know if there will be a bus any more.
我不知道是否还会有公交车。
Nobody knew whether he could pass the exam.
没人知道他是否会通过考试。
注：使用that时，主句的动词一定是确定性（确定性/不确定性）语态，宾语从句的句式结构和句意一定都完整（完整/不完整），因此，在宾语从句中，that可省略 （可省略/不可省略）。
if/whether引导的宾语从句往往句式结构和句意也是完整的，区别在于它们的主语是不确定的。
② 宾语从句的连接代词主要有
who, whom ,whose ,what ,whoever ,whomever ,whosever, whatever, whichever等。
连接代词一般指疑问，但what, whatever除了指疑问外,也可以指陈述。
e.g. :
Do you know who has won this game
你知道谁赢了这一局游戏吗
I don’t know whom you should depend on.
我不知道你该依靠谁。
The book will show you what the best CEOs know.
这本书会告诉你最好的执行总裁该了解些什么。
Have you determined whichever you should buy, a Huawei or Apple smart phone
你决定好是买华为还是苹果的手机了吗
③ 连接副词主要有
when,where,why,how,whenever,wherever,however等。
e.g. :
He didn’t tell me when we should meet again.
他没有告诉我什么时候我们能再见面。
Could you please tell me how you read the new panel
你能展示给我怎么用这个新的操作盘吗
None of us knows where these new parts can be bought.
没有人知道这些的新的零件能在哪里买到。

16．Could you tell me how soon the visitors from the USA ____ (arrive) here
答案：will hand、has happened、catches、will be、were playing、will arrive
throw away扔掉、丢掉 过去式：threw 过去分词：thrown
throw的其他短语：throw out抛出、轰走、扔掉
throw in扔进、添加/投入：作为额外的小费或补充物添加、赠送
throw off摆脱
throw to扔向
throw at对着/冲着……扔
throw和drop、fall的辨析：
drop (使)落下、投下，(使)降低/减少 drop in on sb.突然拜访
drop by sb.顺便拜访
drop down沿着……而下航行、落下
drop out of退出
drop to降至
fall落下、跌倒 fall off=fall down from从……跌落/落下
fall over因失去平衡突然倒下
具体辨析：
Throw 主要指的是有意识地将物体以一定的力量和方向移动，通常涉及到一定的主动性和控制。例如，在体育活动中，如棒球或橄榄球，球员会“throw”球给队友或试图将球投得更远。在日常生活中，我们可能会说“Can you throw the keys to me ”（你能把钥匙扔给我吗？）或者“Try to throw that ball as far as you can.”（试着把你手里的球扔得尽可能远）。
Drop 则更多地指物体由于自身的重量或其他力（如引力）而向下移动，通常不涉及太大的力量或特定的方向控制。例如，当我们说“The weather forecast says the temperature is going to drop below zero tonight.”（天气预报说今晚气温将降到零度以下），这里使用的是“drop”而不是“throw”，因为气温的降低是由于自然过程，而不是人为的投掷动作。在日常生活中，我们可能会小心不要“drop”东西，即不小心让它们落下，而不是故意投掷它们。
总结来说，throw 强调的是有目的性和控制力的动作，通常涉及到一定的力量和方向，而 drop 则更多地描述了由于重力或其他自然力作用下的无意识或被动的移动。
再者，,drop 和fall 都有掉落的意思,例如：
The fruit dropped from the tree.
The ripe fruit fell from the tree.
但是，人摔倒、滑倒、跌倒通常用fall,例如：
Don't walk along the top of the wall; you might fall.
She's not a good rider---she keeps falling off.
{配套练习}
用drop, fall,或throw的适当形式填空。
Her bag is too heavy to carry, so he wants to throw something away.
He fell over and hurt his knee.
The climber slipped and dropped to death.
When autumn comes, leaves turn yellow and fall down from the trees.
remain n.残骸，遗迹
v.仍是，保持不变（作连系动词）e.g. In spite of their quarrel, they remain the best friends.尽管有过争吵，他们仍是最好的朋友。
剩余，遗留 e.g. There were only ten minutes remaining.只剩下十分钟了。
逗留 e.g. They remained in Mexico until June.他们在墨西哥一直住到六月份。
